Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applied to a substrate such as a printed circuit board or chassis of an electronic device, and a plurality of substrates are connected to each other at a substantially right angle or at an angle. The present invention relates to a board fixing tool for fixing a board.

[Prior Art] For example, a printed circuit board is vertically installed on the chassis of an electronic device, and circuits are directly soldered or connected using a connector. When arranging a printed circuit board in an upright manner in this way, conventionally, as shown in FIG.
The vertical board 22 is inserted into a groove inside the holder 21 so that the side edge of the vertical board 22 is held inside the holder 21 for mounting.

[Problems to be Solved by the Invention] Therefore, since the width and height of the holder 21 affect the stability of vertically holding the vertical substrate 22, the width and height must be increased to a certain extent. Therefore, there is a problem that the holder 21 becomes large and the number of elements that can be mounted on the horizontal substrate 20 and the vertical substrate 22, that is, the mounting density of the printed circuit board decreases.

[Means for Solving the Problems] The present invention has been made in consideration of the above points, and solves the above problems by having the following configuration.

That is, the present invention is a board fixing device in which elastic check pieces that are elastically locked in mounting holes provided in the board are provided at both ends of a support member, and the elastic check pieces at both ends are tilted with respect to the support member. It was arranged as follows.

[Function] In the above board fixing device, the elastic check pieces are provided at an angle of, for example, 45 degrees with respect to the support member. The prop member can be used as a support rod to maintain the perpendicular state of both boards, and it is also possible to fix the board at a set angle to the base board other than at right angles. Since it becomes an inclined support rod, it occupies a large area on the board, and it is possible to improve the mounting density of elements on the board.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a front view of the first embodiment of the present invention, in which reference numeral 1 denotes a rod-shaped support member, and elastic check pieces 3 having elastic support pieces 2 at the base are attached to the branch member 1 at both ends of the support member 1. It is installed at an angle of approximately 45 degrees. The elastic non-return pieces 3 on both sides can be inserted into the mounting holes of the printed circuit board while being elastically deformed, and are configured to be locked with their tips protruding from the back surface.

When locking, the step part of the check piece is engaged around the mounting hole, and the elastic support piece 2 elastically presses the surface of the printed circuit board,
A printed circuit board is held between an elastic check piece 3 and an elastic support piece 2.

The substrate fixing device having such a structure is, for example, integrally molded from a synthetic resin material such as nylon, and as shown in FIG. 2, when vertically fixing the vertical substrate 11 on the horizontal substrate 10,
Resilient check pieces 3 at both ends are inserted into mounting holes drilled in each substrate 10.11 and are used to hold both substrates 10.11 in a vertical relationship. That is, the support member 1 of the board fixing tool is placed at the corner of the horizontal board 10 and the vertical board 11.
The IC is arranged at an angle of 5 degrees, and the upper elastic check piece 3 facing laterally is attached to the mounting hole of the vertical board 11, and the lower elastic check piece 3 facing downward is attached to the mounting hole of the horizontal board 10. Fit it in.

Such board fixing tools act as support rods that are installed at an angle, and by installing at least two of them on the horizontal board 10, the vertical board 11 is reliably fixed vertically on the horizontal board 10, and the horizontal direction of the vertical board 11 is fixed vertically. It becomes an extremely effective support member against runout. Further, since the board fixing device occupies a small area on the board, it does not significantly affect the mounting density of the printed board.

FIG. 3 shows a board fixing device according to the second embodiment, and the board fixing device in FIG.
It has elastic check pieces 5 attached at both ends at an angle of about 45 degrees, but the elastic support pieces 6 are small. Further, this substrate fixing tool is also used in the same manner as described above, and for example, as shown in FIG. 4, it fixes the vertical substrate 13 disposed below the horizontal substrate 12 in a substantially perpendicular state.

FIG. 5 further shows a board fixing device according to a third embodiment, and this board fixing device also has a support member 7 and a support member 7 similar to the above-mentioned one.
It has elastic check pieces 8 attached at both ends at an angle of about 45 degrees, and the tips of the elastic support pieces 9 are round and rod-shaped. Further, this board fixing tool is also used in the same manner as above, and for example, as shown in FIG. 6, it is possible to horizontally support and fix the horizontal board 14 like a fence to the vertical board 15 that is erected. .

In addition, the board fixing device of the above embodiment has a width of about 4 cm for the branch member.
The elastic inverse ratio piece was attached at an angle of 5 degrees, but the attachment angle of the elastic check piece can be determined according to the fixed angle of the two boards, which is arbitrarily determined. It can be supported and fixed at any setting angle.

FIG. 7 shows a part of the S5 plate fixing device of the fourth embodiment, and the elastic check piece 16 has the same shape as the first to third embodiments.
The pair of elastic support pieces 17 have different shapes, face in opposite directions, and are provided with their upper portions parallel to the base 18.

FIG. 8 shows a part of the board fixing device of the fifth embodiment, in which the elastic check piece 30 is not connected to the base 31 as in the fourth embodiment. Two pairs of elastic support pieces 32 are also provided.

Both embodiments 4 and 5 do not take up much space and are suitable for use in narrow spaces.

As described above, in the present invention, the elastic check piece and the elastic support piece can be modified in various ways, and are not limited to the shapes of the above-described embodiments.

[Effects of the Invention] As explained above, according to the board fixing device of the present invention, since the elastic check pieces are provided at both ends of the support member at an angle, the elastic check pieces can be attached to the mounting holes of two boards that are aligned at a certain angle. By fitting each elastic check piece, the support member acts like a support ring, and both substrates can be fixed so as to maintain the angle.

For example, by using board fixing devices attached to both sides of the support member at an angle of approximately 45 degrees, a vertical board can be easily erected and fixed on a horizontal board, thereby preventing the vertical board from swinging. The vertical position can be maintained reliably. Furthermore, this board fixture occupies a smaller area on the board than conventional holders, and does not reduce the packaging density of elements, etc. on the board.
